SABnzbd Forums

I queue up some items and all of my drive space is consumed, sab pauses my queue as the drive went 100% full.

Is there an option to stop space allocation so that items can be processes one-by-one.

Not sure what you mean.
SABnzbd doesn't allocate space, although it does need some space for each NZB's admin,
but that's less than 1% of the job's space requirements.
Is it that downloads queue up in the History?
If so, go to Config->Switches and enable the option "Pause Downloading During Post-Processing".

I do have post-processing set to pause the queue.

After having a closer look the problem I'm having is that failed downloads remain in the "incomplete" download directory.

Instead, I would like to delete all temporary folders of any failed status objects including "Invalid par2 files, cannot verify or repair"

You have two choices.
One is to manually remove failed jobs (including files).
The other is to put a "removed failed jobs" event in Config->Scheduler.
